AllLights Puzzle
<< Back to Free Brain Games page

You need a Java-enabled browser to use this applet.    

AllLights is a simple (but not easy) logic puzzle. The object is to turn on all 25 "lights" on the board. This game trains logical reasoning and the ability to visualize spatial relationships.

HOW TO PLAY. Turn on all the squares on the board. Clicking a square toggles its own light and the lights of adjacent squares on and off. Your goal is to click the squares in an order that results in all the squares on the board being lit.

As you play, the number of lit squares displays in the LightOn box. The number of dark squares displays in the LightOff box.

There is no time limit on the game. If you feel like you've messed it up too much to ever solve the puzzle, click the RESTART button to begin again.

This is a great puzzle for building concentration and brain power.

Have fun!
